INKING-MAGHINE.

To all whom it may concern:

Be it known that I, LOUIS J. VAN Gonn- PEN, a citizen of the UnitedStates, residing at the city of Cincinnati, in the county of Hamiltonand State of Ohio, have invented certain new and useful Improvements inInking-l\lachi'nes, of which the following is a specification.

My invention relates to that class of inking machines, designed to inkor color the edges of leather or other material or parts used in theconstruction of some article of manufacture, as for example, shoes,boots and slippers.

One of the features'of my invention is to produce such an inking devicewhich will distribute the inkevenly upon the edge of the material.

Another feature of my invention is to use a revolving wheel todistribute the ink on the edge of the material.

Another feature consists in providing guides or gages formed so thatmaterials of varying thicknesses can be inked.

Another feature consists in the use of an auxiliary ink holding pocketin which the inking wheel revolves.

Another feature consists in the use of a rotary valve capable of beingturned off and on to allow a definite amount of ink to pass into theauxiliary ink holding pocket.

Another feature consists in using an inking wheel peculiarly formed toprevent surplus ink from enroaching upon its inking surface.

In the accompanying drawings forming part of this specification: D

Figure 1, is a view in elevation of one side of the machine, inelevation,

Fig. 2, is a plan view looking at the top of the machine,

Fig. 3, is a view of the forward end of the machine,

Fig. 4, is a longitudinal section taken on line 4-4 of Fig. 2,

Fig. 6, is a cross section taken on line 6-6 of Fig. 1, and

Fig. 7 is a view in elevation of the forward end of the driving shaftfor the inking wheel, broken away.

In carrying out my invention, I provide an arm or extension formed of aflange 1, an offset 2 and a head 3, preferably all Specification ofLetters Patent.

l. shape and forming an ink well or pocket 9 and a valve holding chamber10.

These two castings heretofore set forth, are held together by pins andscrews in any desired manner, but, so that they can be quickly separatedand replaced.

The ink pocket 9 is formed of walls 12 and a bottom 13, and is open atthe top, which may be closed by a cover 14.

It will be seen that the valve chamber is lower than the ink pocket, inthe casting, (see Fig. 4). I

In the valve chamber casting, I provide the valve chamber 15. The inkfrom the ink pocket or well 9 flows into this valve chamber through thepassage way 16. From the valve chamber 15 I also provide a passage way17,'preferably running at an acute angle as shown, which extends to andter minates at 18, at the front face of the valve chamber casting, asshown in Figs. 2 and 4.

In the valve chamber 15, I place a rotary valve 19, provided with apocket20 at the bottom thereof and a handle 21 at the top thereof. Therotary valve is also provided with a peripheral flange 2, 2, at itsupper extremity and slightly below this flange is another peripheralflange 23, which is cut away to form the shoulders 24 and 25; betweenthese two flanges is provided the groove 26.

Near the rotary valve 19, at the top of the-casting 10, I place a finger27, which extends into said groove 26, to keep the rotary valve 19 inposition.

The valve 19 is also provided with port holes 28 and 29 which enter intothe pocket 20 in valve 19. The part 20 holds a definite amount of ink,

On the end of'the shaft 4, on the extreme narrowed end 8, I place theinking wheel 30, which carries and distributes the ink.

This wheel 30 is provided with a rear peripheral ridge or flange 32 anda forward peripheral flange 33, thus a groove 34 is formed between them.This groove 34 is highest at the flange 33 and tapers or inclinesdownward toward the flange '32, at

which point it is the lowest. The front face of this wheel is of a cupor dish shape as shown in Fig. 4. This wheel is stationary on the shaft4, and revolves with it.

To the forward end of the casting 10, next to the valve chamber 15 androtary valve 19, I place a cylindrical shaped hollow extension orauxiliary inkreservoir 35, which is rigidly attached to said casting 10.At the top of this extension I provide an opening 36 and inside thisextension or auxiliary ink reservoir on oneside, I provide a stripper 37(see Fig. 6). The wheel 30 revolves or rotates in said extension or auxiliary ink reservoir, and extends slightly above the same at the forwardend.

On the upper part of the extension or auxiliary reservoir, I place atube or cylinder 38, into which fits and works a small shaft 39 whichcarries a guide plate at its outer end, a spring 41 surrounding saidshaft 39. This guide plate 40 is rounded or cut away at its sides asshown in Fig. 2 and this plate is inclined from the bottom upward.

On the forward end of extension or auxiliary ink reservoir 30, I connectguide plate or gage 42 which rises above the top of the auxiliary inkreservoir as shown and is in alinement with the guide plate or gage 40and its face is inclined same as face of plate 40, sothat the spacebetween said plates will not be vertical, but at an angle as shown inFigs. 1 and 4. The back plate 40 moves forward and backwardso that thespace between said plates will receive varying thicknesses of materialto be inked.

This attachment or device described fully herein is screwed to a basethrough medium of holes 31 and this base carries an ink pot, holding theink, in bulk, which is run into the reservoir 9 by means of a spout, asit is needed. This base and ink pot are not shown and may be of anydesirable form; one form is shown in. my U. S. Letters Patpnt No.1,249,563, dated December 11, 191

If it is desired to fill the pocket 20 with ink, the handle 21 is movedto turn the rotary valve 19 so that the port hole 29 Will coincide orregister with the passage way 16 in inkreservoir 9, thus the ink willflow to fill pocket 20. WVhen it is desired to allow ink to pass intothe auxiliary ink reservoir 35, the handle 21 is turned or moved in anopposite direction so that the port hole 28 coincides or registers withthe passage 17 thus the ink will flow into said auxiliary ink reservoir.When the ink is flowing from reservoir 9 to the pocket 20 the port hole28 is cut off and when ink is flowing from pocket 20, the port hole 29is cut oil, preventing overflow or surplusage of ink. This registrationof the port holes in the rotary valve and the passage ways, isdetermined by thestop pin 43, at the top edge of the valve chamber 15,which limits the revolution or turning of the rotary valve 19, bystriking the shoulder 24 and 25, on the flange 23.

hen the ink wheel 30 is revolving in the ink in the auxiliary reservoir35, the flanges 32 and 33 on said wheel, touch the stripper 37, so thatthe peculiarly formed face 34 on the wheel periphery, and between saidflanges, will be filled with ink. The cup shaped front face of wheel 30is so formed to prevent ink from encroaching or being forced upon theface of the wheel and onto the guide plates or connecting parts, and sothat only the requisite amount of ink will be on the wheel surface forproper work.

The edge of the material to be inked is raced or worked forward andbackward over the periphery of the wheel 30 in the space between theguides 40 and 42; the vise on the wheel periphery 34 will becommunicated to the edge of the material and conse quently the same willbe inked or colored as desired.

The face of the material to be inked is held toward the forward part ofthe wheel 30 nearest the flange 33 of the wheel as less ink being on thewheel at this point, only enough ink will be placed on the edge of thematerial as is required to properly color the same, and inasmuch asthere is more ink on the wheel toward the flange 32 thereof, any surplusink may flow over and be deposited on the back of the material, but thefront, polished or finished face of the material is not soiled orsmeared with ink.

The material can be quickly and readily passed over the surface of theinking wheel between the guides and any shape or contour of material orparts can be inked and any thickness of material.

I do not wish to confine myself to the specific means employed herein tocarry my invention into effect, but may alter and modify the samewithout departing from the spirit and principle of the invention.

What I claim as new and my invention .and desire to secure by LettersPatent, is:

1. In an inking machine of the character described, an ink reservoir, arevolving wheel therein, means for revolving the same, and automaticspacing means for guiding the material aS it is passed forwardandbackward over the surface of said wheel to ink the edge thereof.
